' To all whom it may concern:

Be it known that I, WILLIAM THOMAS DON- NELLY, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Apparatus and Methods for Transporting Solids, of which the following is a specification.

My invention relates to an improved apparatus and method for transporting solids, particularly for transporting c oal.

By the means now available for transporting coal from mines to a convenient or desired point for shipment the cost is so great that the mine operator or owner is compelled -to charge a large price for-it in orderto make a fair profit, and especially is thls the case when it has to be transported for a long distance, and it often occurs that mines are rendered absolutely worthless to the owners on account of the conditions of the country, which render it practically impossible to transport the coal or, if possible, the cost of transportation is thereby rendered so great that the coal cannot be transported and sold at market price.

My invention, therefore, has for its object i to obviate these difficulties by providing a pipe-line through which solid material in a more or less divided state can be transported by means of water forced therethrough, by providing relay devices along the pipe-line for forcing the water and solid material in a mixed condition therethrough, by providing means for controlling the relative quantities 1 of water and solid material entering the pipeline, said means being preferably automatic and controlled bythe specific gravity of the mixture in its passage through one of the relay of water-forcing devices, preferably the initial water-forcing device, and by providing a device of the character -set forth adapted to be operated and controlled below the surface of the water, so as to exclude the entrance o air with the mixture.

In the drawings, Figure 1 is a side view of 'I my device; 2, a plan view thereof; Fig.

3, an end view, partly in section; Figs. 4 and 5, detail views of the governor; Fig. 6, an end view, partly in section, of a modification;

other modification. f

, Corres onding parts in all the igi 1res are denoted ythe-samereference'characters. Referringto the drawings, 1 designates theA hopper or adapted-"f-"contain the solidi.'

comminuted state mixed with water.

The hopper is divided by-"a partition orlwall.- l

and close the opening 6, an thereby re ate the feed of the solid material from the compartment 3.

An outlet-opening 8 is provided atthe bettom of the hopper and is opened or closed by a slidable gate or valve 9 to regulate the feed of the mixture of water and solid material from the hopper into the pipe-line 10, onsterminal of which isconnected with saidpu'tlet and the other terminal leads into therbin'zll, having a grated bottom 12, through fwhich the water runs off, leaving the solid material in said bin in condition for use.

The pipe-line is preferably constructed of sections of pipe and is of a lengthproportioned to the pressure and velocity of the entering solids andwater. As shown, thefirst section of ipe leads from the outlet ofthe hopper to the inlet 13 of the centrifu alpump 14, of which there are a number a ong' the pipe-line for forcing the mixture under pressure and velocity therethr'ou h, and each pump is driven by an indepen ent source of power, as an electric motor 15, the second section leads from the outlet of the pum 14 to the inlet of the second pum 16, the t d section leads from the out et o the pump 16 to the inlet of the third pump 17, and the 9S fourth section leads from the outlet of the disk 24 is provid'edwith a hub 26 ,ha anangular groove 27,'which is engaged by t e ins 28 on the ends of the arms 29,- extending om r ro the collar 30, mounted on the hub. 31 of the disk 19% The pin 32 passes throughelon-ju material to be transported in a more or lessv slidable gate or valve 7V is rovided toggpen 14 is roo attached zo 5 assumer s im 1 is grooradnvlleyhengagad by the inner.

. My process, which is conveniently carried out by means of the above-describ ed .apparatus, consists, essentially, inestablishing a lflew .of -Water through the :line :from there- .ceivingfto the-.delivering Jtenrninal, @introducilt bemnderstoodzthatnwingto the.d 1'f ference in specific avity qf the ma'terialto e water-the ,disks |19 .and f ing rthe solids to lbe ,transported into :the stream .of iiowdn water, :limiting :the intro- .duction of .the .soi ids, preferably ,automatic-- ally, by the change .in .the s peci-fimgravtyof a he -mixturelof water .and so lds .entering the 2li-ne, .amlznally separating the-water I.trofnnthe solids at the delivering-terminalicf the dine.
